Examples of Simonella (s & ¢) (from Panama) sent by O. P.-Cambridge to 
Peckham were returned labelled S. americana. The females which accompanied the 
single male are undoubtedly S. bicolor, Peckh., according to the description and the 
figure of the vulva. The male itself, while obviously rightly mated with the females, 
is certainly not referable to S. americana, Peckh., whether we regard the figures of 
the palpus in beth publications? or the description. The caput in the latter is said 
to be quite black: in the male accompanying S. bicolor it is orange-red, the eyes being 
on black spots. ‘The tibia of the palpus of S. americana in both figures is twice longer 
than broad (rather less, one-half, in Emerton’s figure *), whereas in the male of 8. bicolor 
it is only very slightly longer than broad. The male palpus in §. americana is 
described as black, in 8. bicolor it is white. The clypeus of S. americana is described, 
in 1888, as “less than one-half as high as anterior eyes”; in 1892, as “almost as high 
as the anterior eyes”; while Emerton’s drawing depicts it as equal to one-quarter of 
an anterior eye. ‘The anterior eyes being very large in this group, if the 1892 statement 
be correct, the spider is very different indeed from the male of S. bicolor. 
There is probably a very different species in the Guatemalan region, while it is also 
quite likely that S. bicolor, of which the type came from Venezuela, should extend 
into Panama, whence came the male and females in question. Emerton’s dorsal view 
of the male shows that the example he drew from is closely allied to S. decipiens ; 
whether it is the same as that from which Peckham took his drawing of the palpus,
